SPLICE-JOINT FOR PIPES.

SPECIFICATION forming part of Letters Patent No. 431,697, dated J uly 8, 1890.

Application filed December 23, 1889- Serial No. 334,787. (No model.) i

To (1 whom it may concern.-

Be it known that I, FRANZ CONRAD KiiM- MEL, of Baltimore, in the State of Maryland, have invented certain new. and useful Improvements in Splice-Joints for Pipes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to certain improvements in metal pipes or tubes.

The object of the invention is to produce an improved metal pipe made in longitudinal sections in such a manner that the sections can be packed together into a small compass for transportation, and also to provide means for uniting said sections to form a strong and durable pipe.

These objects are accomplished by and the invention consists in certain novel features of construction and in combinations of parts more particularly and fully set forth hereinafter.

Referring to the accompanying drawings, Figure 1 is a perspective of a length of the improved pipe provided at one end with a bend. Fig. 2 is a section of the bend on the line A B, Fig. 1. Fig. 3 is a section on line C D, Fig. 1. Fig. at is a section on line E F, Fig. 1; and Figs. 5 and 6 are end views, respectively, of a corner and a side splice. ,Fig. 7 is a detail perspective of the joint between the pipe-sections.

The pipe, as shown, is rectangular in crosssection, and the straight portion thereof is formed of the two longitudinal sheet-metal sectionsab, one of said sections a forming two and a part of the third side of the pipe and the other section b forming the fourth and remaining portion of the third side of the pipe. These sections are secured together at their longitudinal meeting edges to form a perfect pipe by the longitudinal central side splice c and the corner-splice cl, each splice being bent from a single strip of sheet metal of suitable width, so as to form the main outer portion 6 to overlap the outer faces of the meeting edges of the pipes-sections, the opposite edges of said strip being both correspondingly bent back against the inner face of said portion 6, and then doubled back against themselves again, so as to form the similar oppositelyopening sockets or seats f f and the inner longitudinal edges g g, which extend beyond the edges of portion 6 and bear against the inner faces of the edges of the pipe-sections.

From the foregoing it Will be readily observed that a splice is provided for each pair of meeting edges of the pipe-sections, and that said edges are fitted singly into the opposite sockets f, with the outer portion of the splice overlapping and fitting the outer faces of both, meeting and covering the joint between the same, and the inner edges g fitting against the inner faces of the pipe-sections, thereby firmly holding said sections together, and the sections can be firmly and rigidly secured in the splice by rivets h or other means passed through the said pipe-sections and ends g of the splice, as shown. Of course it is evident that the form of the splice can be varied according to the shape of the pipe. For instance, the center side splice c is formed with the sockets ff in the same plane; but where the splice is to be used at a corner the sockets extend at angles from each other, as shown by splice d, where the sockets extend at right angles from each other and the portion e is bent to a corresponding angle. In practice the pipes are thus formed of certain lengths and the different lengths are united by rectangular continuous transverse splices t', provided with opposite sockets f f, into which the adjoining ends of the pipe-sections fit and are secured, as shown in Figs. 1 and 3,thereby firmly uniting the pipe-sections and forming a continuous pipe. Bends or elbows are constructed angularly, as shown in Fig. 1, with the straight ends connected by the-diagonal length. The bend is composed of two fiat side pieces jj, extending the length of the bend and corresponding in shape to the shape of the same, and a top plate It and a bottom plate Z, correspondingly bent, the four longitudinal sections of the bend being united by four splices. The two top splices are split at one side, so that the splice can be bent to form the angles, as shown, and the two bottom splices are correspondingly split to allow their ends to be bent to the proper angle. The ends of the bend are connected to the straight sections by means of continuous splices i, beforse described, and suitable fastenings, such as 7/. h

Pipes constructed after this invention are exceedingly strong and durable and adapted for any use or purpose where. such a pipe is needed.

It is evident that this invention is not limited to any particular number or form of iongitudinal sections, and that various changes might be made in the form and arrangements of the parts described without departing from the spirit and scope of my invention; hence I do not wish to limit myself to the exact construction herein set forth.

What I claim is 1. A pipe the body of which is formed of two or more longitudinal sections and independent splices connecting said sections at their meeting longitudinal edges, said sections being composed of independent sheets having substantially flat edges, as described.

2. A pipe the body of which is formed of longitudinal sections of sheet metal having substantially fiat edges and splices uniting the longitudinal meeting edges of said sections, securing the sections together, said splices covering the joint between said sections and overlapping the inner and outer faces of both meeting edges, and means for securing said sections to the splices, substantially as described.

3. A pipe composed of a plurality of sections, each of which consists of separate flat sheet-metal pieces having substantially flat edges and splices uniting the longitudinal edges of said sections, in combination with a socketed joint interposed between the ends of the sections of the pipe, whereby the sections are united.

4:. An angular pipe the body of which consists of separate similar flat sheet-metal side pieces and corresponding sheet-metal back and throat pieces, and corner-splices uniting the side and throat back pieces and located at the longitudinal meeting edges of the same, substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
